vue启动服务Cannot GET /问题

在启动vue项目时，出现Cannot GET /提示，原因是之前修改了config下index.js的assetsPublicPath

错误提示：
Refused to load the image 'http://localhost:8075/favicon.ico' because it violates the following Content Security Policy directive: "default-src 'none'". Note that 'img-src' was not explicitly set, so 'default-src' is used as a fallback.

解决方法：
将config下index.js中的 assetsPublicPath: './'改成`assetsPublicPath: '/'即可。

正常启动
